TO WHOM IT MAY- CONCERN:

Be it known that I, MARSHALL S. CURTISS,.0f the town of Bradford, in the county of Stark, and State of Illinois, have invented anew and useful Improvement for Coupling and Using a Plough in Connection with a Two-Wheel Carriage; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and the letters of reference marked thereon.

The nature of my invention consists in attaching to atwo-wheel carriage, invented and built for the purpose, a coupling, so that any common plough may be readily attached to the carriage in such manner that the driver, while seated upon the carriage, can guide the plough with as muchaccuracy, and do his work as well, as if he were at the tail of the plough, guiding it by its handles. It is so constructed and combined with the carriage that it will permit either wheel of thelcarriage to rise or lower so as to pass over any ordinary obstruction, or sink into a hollow in the ground without in the least interfering with the movement of the plough. Further, it is so constructed that the driver, by displacing a lever, or changing from one notch to another, may, by his own weight, in connection with the leverage obtained bymeans of a crooked axle of the carriage, raise the plough out of the ground without the driver having to leave his seat. This operation is performed with great facility and withperfect ease.

Figure 1 is a perspective View, taken on the land-side of the plough, showing the carriage and plough, with their several attachments. when connected and ready for use.

Figure 2 is a perspective view of the same, taken from the mould-hoard side of theplough, representing the plough elevated above, the ground, as when passing-to and from the field, or in passing over obstacles.

Figure 3 is an elevation of the slotted guide and its attachments, through which the end of the plough-beam passes, and is allowed to have a vertical motion.

Letter A represents the wheels of thecarriage, the land-side wheel of which should be smaller than the other, in order that the axle E of the carriage may be level while .one wheel runsin the furrow. Letter B represents the plough, which may be made in any of the usual styles of constructing ploughs, and is made to,

operate in rear of the axle E, by means of the following devices: I use a curved-and slotted arm C, hinged to the axle E as a supportand guide, through which the beam of the plough B passes, and which said arm is permitted to have an easy horizontal motion betwecnthe ears Land-thus allowthe plough to move forward in a direct line, while the carriage thereto'attached may have a lateral motion. This arm 3 is also used to lift the plough B out of the ground, as seen in its position in fig. 2. In order to accomplish this latter object, a leirer, I), is rigidly attached to axle E, and is made to rest in notch P of seat F when the plough is in the ground, and in notch O in same seat: when the ploughis out of the ground. The forward guide 2 is made to support the end of the beam B, and is allowed to have a lateral motion between the framework Mattached to tongue G of the carriage by means of armed sockets N N", to which said guide'2 is attached. The seat F rests upon the tongue and itsattachments in front of the crank-axle E, by which means theweight'of the operator will cause the said axle E to turn forward when the lever D is removed from notch P, and adjusted in notch 0, so as to lift the plough B out of the ground.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

, 1. The curved and slotted arm 0, its form and manner of adjustment between the ears I, combined with the plough-beam B, substantially as and for the purpose set forth.

2. The forward guide Q, combined with armed sockets N, arranged to allow the forwardend of the ploughbeam B to have a lateral and vertical motion, substantially as set forth.

3. The arrangement of the seat F, in front of the crank-axleE, combined with lever D, the whole being arranged to set plough B in the'ground, or lift it out of the ground, as described and set forth.
